parachute should the aeroplane bedisabled. i

The main object of our invention is to provide a device which canbeeasily attached to the present desi n of aerial machines.

A further object is to provide a device which will have very littleresistance against the forward motion of the aerial craft on which it ismounted.

yA further object is to provide a device vwhich can be easily andquickly thrown into operation.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of be hereinafter fullydescribed, illustrated in the accompanying drawings, and pointed out inthe claim hereunto appended.

Figure 1 shows a perspective side view of our invention in closedposition. Fig. 2 shows a view oit' the same in open position. Fig. 3shows an enlarged' sectional view of the operating mechanism.

Referring to the drawings like numerals designate like parts in thevarious drawings.

ll indicates a portion oi. the aeroplane, preferably the top, on whichour invention is adapted to be mounted. 1

5 is a cylindrical vertical positioned member having, a flangedlower",7`4 end through fastening means attach it to the portiontifoiIthe aeroplane 4f. Centrally inside this member is an upright pipe or rod6 having a small notch 7 on its rear side.` In the lower portion ofmember 5, we provide an annular rin B securely attached to the innerside of said member. 9 is a 'compressible coil spring having a platesecured at its top and-bottom, the bottom plate adapted to rest on theannular ring 8. The section y below this annular ring 8 is adapted toreceive a coil of rope or cable 10, the use of which rope or cablewillbe hereinafter explained.

11 is a parachute of any particular design arts as will themselves inparallel vrelationship when.

free to do so. 19 is a spring attached to the rear of part 16, and itsfree end is adapted to engage in the notch 7 when the part 1Gb ispressed down on the upright 6.I 20 is a ring slidably. positioned aroundthe lower end of part 16?. Arms 21 connect this ring 20 to thehinge-portion 17 the connection to portion 17 being so as to act as aneccentric.

From this description and the accompanying drawings, itwill be seen thatwhen the parachute-is in parallel relationship to the aeroplane, thering 20 is pressed down so as to allow the end ofthe spring 19 to engagein the notch 7 and thus securely hold this end of the device down. Whenthe top end of the parachute is freed the tension springs 18 will drawit so as to bring the arts 16 and 16b in parallel relationship. n doingthis the hinge-portion 17 in turning pulls l disengaging the end ofspring 19 Jfrom notch 7 The compressed coil spring 9 will now shoottheparachute into the air aboveA all the working parts of the aeroplane.The parachute has suitable springs 22 or other means to throw theparachute open. The rope or cable 10 is attached at 23 and eX- tendsdown to the lower portion of the cylindrical member 5 as hereinbeforementioned. A small check rope 24 is attached to the cable or rope 10 andto the keeper 1 2 sothat when the rope or cable is drawn in tight, thiskeeper 12is drawn down, thus freeing the parachute for opening.

25 is a cylindrical memberV mounted at .a suitable position ontheplane'fl. 26 is a coil spring having a bearing secured at its top.This coil spring is adaptable orcompress ing into the cylindrical member25. The bearing is adapted to receive the upper end toengage the ends ofthe parachute 1.1 and the other end spring-tensioned by the spring l 28.29 is a trip-rope attached to the springtension of the trip-member 27and eXtending down to a suitable position Where the operator can easilypull the same.

From the foregoing it is thought that the construction of our inventionWill be clearly understood, and therefore a more extended explanationhasl been omitted.

A safety attachment for aerial machines consisting of a parachute, atripmember adapted to engage at the free end of the parachute, means.for disengaging said tripmember, a means forholding the other end ofsaid parachute, a means for releasing said holding means when saidparachute is in a vertical position, av means for releasing the openingof said parachute, an attaching means between said parachute and saidair 20 craft, and a means. for shootlng said parachute into the air.

In testimony whereof We ax our signatures in the presence of twoWitnesses.
